JOSEPH TREMIBLAY, OF ST. JOHNSBURY, VERMONT, ASS IGNOR OF ONE-HALF T0GEORGE CLINTON FRYE, OF ST. JOHNSBUBY, VERMONT.

BOX-OPENER.

To all whom it may concern:

Be it known that I, JosnrH TREMBLAY, a citizen of the United States,residing at St. J ohnsbury, in the county of Caledonia and State ofVermont, have invented certain new and useful Improvements inBox-Openers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention contemplates the construction of a nail puller,especially for opening boxes, provided with a removable claw mem' herand a hammer adapted to be reciprocated against the claw member forquickly removing nails.

One of the objects of the invention is the production of a box openercapable of being used for pulling nails from boxes or other articles, orcapable of being used for an ice pick, and provided with a removabletool set at an oblique angle to the shank of the device.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claim,and in the drawings, in which,

Figure 1 is a perspective view of my improved device, with certain partsbroken away; Fig. 2 is a longitudinal sectional View of a shank head;and Fig. 3 is a detail perspective view of a removable ice pick tool.

In the drawings 1 denotes the shank of my improved tool, and is formedwith an offset, 2, which is longitudinally pierced by an aperture, 3,which extends from the lower end of the shank to the upper end of theoffset and at an oblique angle to the shank. The shank head, 2, isformed integral with the shank 1 and is adapted to receive the stem, 3,of a clawed tool, 4, which may be secured thereto by screw threads, orsimilar means.

When the clawed tool, 4, is inserted in the offset, 2, said tool willoccupy an angular position with respect to the shank, 1, and said ofisetis flattened at its upper portion to receive the blows of a hammer, 5,and said hammer is formed with a longitudinal bore, 6, and an enlargedhead, 7 and is slidably mounted on the shank, 1, so that the same may bereciprocated back and forth on Specification of Letters Patent.

the shank for the purpose of delivering blows on the head of theofl'set, 2.

The shank, I, is preferably formed of suitable length to permit ofconsiderable movement of the hammer, 5, and is reduced at its upper endto receive a handle, 8. The handle, 8, is locked to the reduced end ofthe shank, 1, by means of a washer, 9, arranged to engage the shoulder,10, of the shank, 1, and a second washer, 11, arranged to engage theupper end of the handle, 8, and be locked thereagainst by arivet head,12, formed on the shank, 1. The hammer, 5, is limited in its upwardmovement by the shoulder, 10, and in its downward movement by theoffset, 2, and the outer side of said offset occupies an angularposition with respect to the shank, 1. The clawed tool, 4, is adaptedfor pulling nails from boxes or other articles and may be forcedinwardly on the wood of a box by the reciprocation of the hammer, 5, onthe shank, 1, and using the shank as a lever with the offset as thefulcrum.

Vhen it is desired to remove the clawed tool, 4, all that is necessaryis to force the stem outwardly from the aperture, 3, by turning theclawed tool, 4, in the offset 2, or inserting an instrument through theupper end'of the aperture, 3, and exerting pressure against the stem ofthe clawed tool.

lVhen the clawed tool is removed from the shank an ice pick, 13, or asimilar tool formed with a chisel end, may be inserted in the aperture,3.

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claim.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is:

A box opener comprising a shank having an integral angular foot with alaterally ofiset heel formed integral therewith, said foot beingprovided with a threaded aperture extending through the same at anoblique angle to the shank, a hammer formed with Q e eneeo an enlargedhead mounted to slide upon tween the Washers, said hammer adapted theshankand arran ed to be reciprocated to be limited in one direction bythe lower against the offset hee a tool having a re- Washer. ducedthreaded shank to engage the thread- In testimony whereof I havehereunto set ed anerture in the foot, said tool having 3 my hand inpresence of two subscribing 15 shou der formed by the reduced threaWitnesses.
